Description

Double card

The present invention relates to a kind of double card, it comprises one first combing cylinder, be used for the raw fiber that is delivered to is wherein carried out preliminary combing effect, with one second combing cylinder, be used to receive the fiber of the processing that produces by the first combing cylinder, so that it is carried out further combing effect, thereby improvement is to the processing of fiber.

It is many year that the duplex carding machine has used, is the Mark5 type duplex carding machine that the Crosrol Co., Ltd by Britain Halifax city (Halifax) produces at a commercial very successful example.Obviously, have two independently the structure of combing cylinder (relative) with the carding machine that uses an independent combing cylinder mean and can obtain more combing effect, thereby improved the directionality of fiber and improved the cleaning efficiency of operation, promptly, improved the shared ratio of waste material that is eliminated away in that the useful fiber of removing in the thing is reduced to the MIN while.

Shown in Figure 1 in the Mark5 type duplex carding machine of Crosrol Co., Ltd such as the accompanying drawing, and will be used as background knowledge of the present invention and be introduced.The duplex carding machine is divided into the part of two orders, a upstream comb unit is wherein arranged, be known as " breaker ", usually shown in reference number 10, be used for receiving the fiber raw material of supplying with by material loading skewed slot 11, and fiber carried out preliminary carding operation, then with these fibre transportation to the downstream comb unit, i.e. " condenser card " shown in reference number 12, carry out further combing effect, and then the fiber web discharging that will handle and be sent to next handling machine (not shown).

Breaker 10 comprises the first combing cylinder 13, from the fiber raw material of material loading skewed slot 11,, be transported on the first combing cylinder 13 by feed arrangement 14 and licker-in 15, under the assistance of the removable cover plate 16 of a cover, the fiber web that cylinder 13 is transported carries out carding operation.Then, the fiber of handling is taken off by doffer 17, by means of a cover transfer roller 19 (with the grating roller) and a licker-in 20, is transferred on the second combing cylinder 18 in the condenser card 12.Then, the second combing cylinder 18 and removable cover plate 21 actings in conjunction of a cover are taken off from cylinder 18 by doffer 22 through the last fiber of handling, by means of 23 dischargings of guipure device and be sent to other handling machine (not shown).

When using double card, need a lot of transmission/grating roller, will be sent on the downstream combing cylinder from upstream combing cylinder through the fiber of part combing, this has become the common practice in cotton (with the like fibrous material) the carding machine production technology.

Owing to this reason, the double card of type shown in Figure 1, many fibre transportation rollers are equipped with in the space between upstream and downstream combing cylinder.General knowledge shows, any minimizing of roller quantity in this zone all can produce the influence that is difficult to accept to the processing quality of fiber, has especially reduced the effect of the combing effect of downstream combing cylinder thereafter.

Two combing cylinders 13 of duplex carding machine and 18, installation fixed relative to one another for example can be by the

device

10 and 12 that is bolted together.Leave the spacing of standard between licker-in 15 on the first combing cylinder 13 and the material loading skewed slot 11.Spacing commonly used between the feed arrangement 14 of material loading skewed slot 11 and licker-in 15 is about 14 inches.

Yet, for duplex carding machine (the same) with all types of combing machines, need carry out regular cleaning/maintenance to the parts of machine, because the tight connection between the breaker unit of duplex carding machine and the condenser card unit is arranged, the i.e. first combing cylinder 13 and accessory (licker-in thereof, doffer and removable cover plate) and the second combing cylinder 18 and associated components thereof between tight connection, be difficult to obtain enough passages, with the parts of the interface both sides that arrive two combing cylinders, promptly be sent to the zone of Unit second from first module through the fiber of section processes.

Therefore, the purpose of one aspect of the present invention is, a kind of simple method is provided, and relative adjustment (when not working) is carried out in the position of two combing cylinders of double card, thereby the interface zone between two combing cylinders provides the passage that is used for maintenance washes operation of increase.

Therefore, according to a first aspect of the present invention, provide a kind of double card, be used for the fibrous raw material that is delivered to is wherein carried out carding operation in proper order, above-mentioned carding machine comprises a fibrous raw material feeding device and first, second comb unit, wherein:

First comb unit comprises raw-material first a combing cylinder that is used to receive from above-mentioned feeding device, first licker-in that is used for the fiber raw material from above-mentioned feeding device is sent to the first combing cylinder, and with the first combing cylinder collaborative work first the cover cover plate;

Second comb unit comprises one second combing cylinder, and overlaps cover plate with second of the second combing cylinder collaborative work;

It is characterized in that: first and second comb unit can be slided between operating position and non-operative position relatively, and when the operating position, they are collaborative work each other, thereby fibrous raw material are carried out the carding operation of order; When the non-operative position, between two unit, form an aisle space, thereby can maintain/cleaning operation the parts of each unit near aisle space.

Therefore, according to the double card of first aspect present invention, when being adjusted to its operating position, can be used for carrying out the carding operation of order, and can produce the obtainable advantage of the use first and second combing cylinders.Even but need carry out regular M R, as regular cleaning, perhaps or even irregular maintenance, necessary relative adjustment is carried out in the position of first and second comb unit, thereby between two unit, form an aisle space, also be a very simple thing, the operator can the admission passage space in, come parts contiguous in each unit are keeped in repair.

As for first and second comb unit can be relatively moved, require not strictly, two unit can all be movably, perhaps first and second comb unit one of them fix, and another is movably.

Yet in the optimal placement scheme, second comb unit is that downstream units is hard-wired, and first comb unit is set to movably.

Usually, between the upstream extremity of first comb unit and feeding device, determine a space, fiber raw material suitably can be sent to the first combing cylinder from feeding device.Feeding device generally includes a material loading skewed slot, and one is used for raw material are sent to the device of first licker-in from skewed slot, and it may comprise a feed plate and cotton-supplying roller again.The space of the first comb unit upstream extremity, usually be about 14 inches, can be used to make first comb unit to move to the non-operative position, occupy this space of upstream extremity, thereby between two unit, produce the aisle space of same widths away from second comb unit.

For the fiber that will handle is sent to the second combing cylinder from the first combing cylinder, can adopt any suitable conveyer, in the optimal placement scheme, conveyer just comprises the direct transmission from first doffer that combines with the first combing cylinder to second licker-in that combines with the second combing cylinder.

Therefore, in the optimal placement scheme of first aspect present invention, first and second comb unit can occupy with the known fixed installation floor space much at one of duplex carding machine (when being in the operating position, between the licker-in of the material loading skewed slot and first comb unit, has identical upstream spacing), but when being adjusted to the non-operative position, utilize the space, upstream that has existed, can allow first comb unit to carry out necessary relative motion, thereby can clean or maintain operation.Obviously, between two unit, produce an aisle space, greatly simplified method near the component parts that needs in the comb unit to clean and/or maintain.

In the arrangement of the best, first comb unit is installed on the guide rail, guide rail can be controlled first comb unit and carry out essential linear movement between operating position and non-operative position, and have at least a guide rail to engage, so that lateral restriction essential in the motion to be provided with the flanged roller that supports first comb unit.And another root guide rail can have simple vertical support joint with the relevant one or more rollers on being positioned at the unit opposite side.

Any suitable power-actuated device can be used, so that first comb unit is carried out essential linear reciprocal movement between work and non-operative position.As just example, the piston device that can adopt hydraulic pressure or air pressure to drive.

A first aspect of the present invention mainly is about the relative adjustment motion between first and second comb unit in the duplex carding machine is provided, and the most preferred embodiment of first aspect provides the fiber that will handle by the licker-in of the doffer of first comb unit and second comb unit to be sent to the direct transmission of second comb unit from first comb unit.Yet, according to a second aspect of the present invention, the feature of relative motion can be removed between first and second comb unit, but by means of and the doffer that combines of the first combing cylinder with and the licker-in that combines of the second combing cylinder between direct the contact, but have the fibrous raw material that will handle directly is sent to the second combing cylinder from the first combing cylinder characteristics equally.Have now found that this can produce surprising technological improvement to the transmission and the processing of fibrous raw material.

Correspondingly, in a second aspect of the present invention, provide a kind of double card, it can be used to the fiber raw material that is delivered to is wherein carried out carding operation in proper order, and above-mentioned carding machine comprises:

The feeding device of a fiber raw material;

One first combing cylinder is in order to receive the raw material from above-mentioned feeding device;

One first licker-in is in order to be sent to the first combing cylinder with fibrous raw material from feeding device;

The first cover cover plate, it and the first combing cylinder collaborative work;

One first doffer is in order to take off the fiber of handling from the first combing cylinder;

One second combing cylinder;

A licker-in is in order to be sent to the second combing cylinder with treated fiber from the first combing cylinder;

The second cover cover plate, it and the above-mentioned second combing cylinder collaborative work;

The conveyer that the fiber that is used for handling takes off from the second combing cylinder.

It is characterized in that: the transmitting fiber tow that the doffer that combines with the first combing cylinder directly will be handled is delivered to second licker-in that combines with the second combing cylinder.

Double card according to second aspect present invention, in processing to fibrous raw material surprising effectively, wherein cautiously remove and be used for and be sent to many cylinders (just as at known double card) of the second combing cylinder from the first combing cylinder through the fiber of part combing, in fact can't cause producing underproof sliver, at least on the fabric meaning that the yarn that is spun into by sliver finally is made into, in experiment, be proved to be and had higher quality.

Why can produce beyond thought result like this, its reason also imperfectly understands, but it is generally acknowledged it may is because following theoretic imagination, or both have concurrently, or just one of them:

1. in known double card, the existence of many transmission and other cylinder has produced draw, helps to increase before the fiber through section processes is transferred into the second combing cylinder its depth of parallelism.

2. the action of known double card intermediate roll helps to make fiber crimp before fiber is transferred into the second combing cylinder.

At present, these theoretic imaginations only are to infer, but for following state, but provided possible explanation: promptly why according to the carding property of the double card of second aspect present invention no less than known double card, otherwise, at the fiber product that the improved combing of performance is provided (be used for being spun into thereafter sliver, be processed into cloth then) aspect, even it is can be more ineffective, also effectively same at least.

Therefore, before fiber is transferred into the second combing cylinder, when bigger fibre orientation may be considered to the feature of an expectation, it is generally acknowledged, in known double card, in fact this may reduce the effect of cleaning action, and this cleaning action is to act on fiber by the cover plate and the second combing cylinder collaborative work thereafter, wherein be attached to the existence of the not parallel fiber on the cover plate of the second combing cylinder, in fact can strengthen cleaning action.

On the other hand, in known double card, the trend that fiber curled before being transferred into the second combing cylinder can cause the processing of the fiber between the cover plate and the second combing cylinder and the validity of cleaning are reduced.

Fig. 2 below with reference to the accompanying drawings, 2a and 2b as just example, introduce a most preferred embodiment of the double card of foundation of the present invention first or second aspect in detail, wherein:

Fig. 2 is a schematic side view, illustrates according to double card of the present invention.

Fig. 2 a is a detailed view, has shown a part of carrying out the linear guide apparatus of linear reciprocal movement in order to a comb unit in the control double card with respect to another comb unit;

Fig. 2 b is another detailed view, and is similar with Fig. 2 a, shown another part of guide rail guiding device.

At first with reference to the Fig. 2 in the accompanying drawing, shown in reference number 10, it comprises one first to foundation double card of the present invention usually, it is upstream comb unit 101, with one the second, promptly the downstream comb unit 102, in order to fiber raw material is carried out the carding operation of order.

It has a fiber raw material feeding device, preferably adopts the form of material loading skewed slot 103, by means of a common feed plate 104 and the cotton-supplying roller 105 and first licker-in 106, raw material is delivered to first comb unit.

First comb unit 101 has one first main combing cylinder 107, and fiber raw material is put thereon by licker-in 106, and the first

cover cover plate

108 and 107 collaborative works of combing cylinder carries out preliminary combing to fiber and handle.In the optimal placement scheme, as shown in the figure, the first cover cover plate 108 comprises the cover plate that a cover moves, and this is that those people that are skilled in technique usually are very familiar to, and needn't be described in detail at this.

In order to take off the fiber of handling, also has one first doffer 109 from the first combing cylinder 107.

Second comb unit 102 comprises 110, one second licker-ins of one second combing cylinder, 111, the second cover cover plate 112 and one second doffers 113.

In use, preliminary combing effect puts on fiber raw material by the carding element of first comb unit 101, is transferred into second comb unit 102 then through the fiber of section processes, handles to accept further combing.

First and

second comb unit

101 and 102 are adjusted to position fixed relative to one another usually, like this, will produce continuous fabaric mterial flow at the upstream and downstream end of duplex carding machine.A space G1 is arranged between material loading skewed slot 103 and cotton-supplying roller 105 usually, and in typical fixed duplex carding machine was arranged, width was approximately 14 inches.Yet the border region between the upstream extremity of the downstream of first comb unit 101 and downstream comb unit 102 has an adjustable space G2.This has just determined the gap between first doffer 109 and second licker-in 111, and can adjust by changing fixed scotch in one of them unit and the joint between the scotch regulated in another unit.In illustrated arrangement, a fixed scotch 114 is arranged in second comb unit 102, in first comb unit 101, there is one can regulate scotch 115.To regulating the adjustment of scotch 115, can change framework between doffer 109 and the licker-in 111 or the width of space G2.

Yet, in order to produce a path clearance in first and second comb unit, to realize regular or irregular cleaning/maintenance operation, as shown in the figure, first and

second comb unit

101 and 102 are arranged to and can relatively move between operating position and non-operative position, when the non-operative position, just form a path clearance between these two unit.In the optimal placement scheme, as shown in the figure, second comb unit 102 is fixed, and first comb unit 101 then is can be linearly moving along guidance system.Guidance system comprises a pair of guide rail that separates each other 120, and support wheel can slide thereon, to support first comb unit 101.Fig. 2 a is depicted as the flanged roller that engages with guide rail, so that the side direction guiding constraint to be provided, and plane vertical support just shown in Fig. 2 b.

In order between operating position and non-operative position, to move first comb unit 101, need a suitable Power Drive Unit is installed, only schematically show in the drawings, shown in reference number 116 with a piston and air cylinder device (air pressure or hydraulic-driven).

First comb unit 101 motion to the right can occupy standard voids G1, makes space G2 increase same size then, thereby enters for the operator that this zone is carried out regularly or other maintenance, cleaning operation provide a unimpeded inlet between two unit.Finish after maintenance/cleaning operation, first comb unit 101 is back to by fixed scotch 114 and can regulates the initial gap setting that scotch 115 is determined, be that piston cylinder device 116 is worked always and engaged again until two scotchs, and confirm that initial setting is adopted once more.

Therefore; the duplex carding machine that in Fig. 2, schematically shows; usually can occupy the identical floor space of traditional design with the duplex carding machine of first and second comb unit that fixed installation is arranged; path clearance can form by occupying the space that occurs by any way, as the space between material loading skewed slot and the cotton-supplying roller.

Reach the relative adjustment between first and second comb unit shown in schematic diagram as mentioned above, only comprise an example of first aspect present invention.In a second aspect of the present invention, the characteristic of relative adjustment can be saved or provide on demand.According to the example of second aspect present invention, can realize the direct transmission of fiber by means of the direct transmission between doffer 109 and the licker-in 111 from first comb unit to the second comb unit.

This of fiber directly transmits the transfer roller that is different from bunchiness (as the design according to the Mark5 type duplex carding machine of the known Crosrol Co., Ltd as shown in Fig. 1), and wonderful technological merit is being provided aspect the fibrous raw material processing.

Use different cotton fiber raw material samples, compare, carried out the contrast property testing with Mark5 type duplex carding machine and the new design of the double card of the present invention of foundation as shown in Figure 2 (between doffer and licker-in, existing direct transmission).Be understandable that these only are preliminary tests, can further investigate in the future, but may produce different results.Yet, even from these preliminary tests, also can clearly find out, use most preferred embodiment of the present invention, at least in some cases, can obtain the important techniques advantage aspect the processing of fibrous raw material.

The cotton that the test of duplex carding machine adopts three kinds of different places of production, have a different characteristics carries out.The Turkey cotton is staple fibre, polymictic cotton; CIS (CIS) cotton is the cotton of middle fiber, relative clean; The Australia cotton is long fiber, clean cotton.

Initial test is on existing Mark5 type duplex cotton carding machine, is carried out before its quilt repacks double card of the present invention into, and this situation that has guaranteed steel wire is identical with being provided with.

Three kinds of combing productivity ratio that adopt are: 65Kgs/hr, 85Kgs/hr and 105Kgs/hr.Twice by drawing frame after, weaving before, sample is spun into ring spinning and open-end yarn.

The linear density of yarn is 12 yarn counts (s) open-end yarn and 16 yarn counts (s) ring spinning, and for refining yarn, yarn count then is 38 yarn counts (s) open-end yarn and 34 yarn counts (s) ring spinning.The spun yarn number always is not applicable to the kind of the cotton of being spun, but in the spinning yarn count process of spinning, any minimum defective all can be very showy, and can itself not covering by yarn.

The test result of open-end yarn shows that double card is equal to or is better than the duplex carding machine.If the Wu Site test instrument is not calculated as cotton knot with impurity particle, the ring spinning test result of double card will be better than the duplex carding machine.Contain more impurity in the yarn of double card combing is can be received: because after cylinder is installed new steel wire and made its speed optimization, this problem can be eliminated.

When being in the single jersey form, the real advantage of double card just can display.It is 34 yarn counts (s) Nec ring spinning that spinning requires the strictest yarn, and this yarn is only the fabric that can show any significant differences.Observe this kind fabric on the blackboard, the double card fabric has totally cloth cover preferably, can only see less black background by the gap in the yarn.Whole fabric seems that the quality more regular and more less than duplex carding machine fabric is inhomogeneous.And duplex carding machine fabric face it seems seemingly to have more " break-in " (mean seem to wear and tear more serious-can see the spot of wildness) effect than double card fabric.This wearing and tearing mean that in fact usually this fabric is easier to balling-up.Observe this kind fabric on the blank, the double card yarn is impure more usually, but as preceding described, this problem can be resolved.

Fabric by spinning yarn count open-end yarn spinning demonstrates, and in fact the double card fabric is better than or is equal at least duplex carding machine fabric, and this depends on type of cotton and the adaptability that spinning yarn count open-end yarn is spinned.The impurity content of fabric is identical with the double card fabric or slightly poorer than it.

By the double card fabric of 16 yarn counts (s) ring spinning spinning, the same with duplex carding machine fabric good with regard to the uniformity and cloth cover, or in fact better in some cases than it.The content of impurity is identical with the double card fabric or better than it to a certain extent in the duplex carding machine fabric.

Thick open-end yarn fabric is to require least strictly in the fabric of all productions, is difficult to this moment distinguish double card and duplex carding machine sample, and two kinds of pck counts seem all to have preferable quality.

Attention: to the fabric evaluation carried out of external behavior intuitively, do not have measuring instrument to judge and classification to the outward appearance of fabric with the grade separation method of non-quantification.Judgement to the fabric external behavior depends on trained eyes, but this is a kind of measurement of non-quantification, and all VIPs in the retail manufacture of needs dependence clothes and cloth judge its quality.

In above explanation of consulting the Fig. 2 in the accompanying drawing, introduced doffer H and licker-in E, wherein each all is installed in one independently on the combing framework sub-unit, and two sub-units can move relative to each other.

Yet if desired, transfer roller can be installed between doffer H and the licker-in E, thereby improves the quality through the product of combing.This is almost not had or opposite traction effect is realized by desirable between two comb unit.
